This mirrors a similar side fix for the API server authenticator.
Don't trim the issuer URL provided by the user since OpenID Connect
mandates that this URL exactly matches the URL returned by the
issuer during discovery.
Not test updates since this is already tested by the go-oidc client
package.

Add GUBERNATOR flag which produces g8r link for node e2e tests
When you run 'make tests-e2e-node REMOTE=true GUBERNATOR=true' outputs a URL to view the test results on Gubernator. ~~Should work after my PR for Gubernator is merged.~~
@timstclair
When node is deleted, attach-detach controller cache may contain stale
information of this node, and update node status fails in reconciler
loop. But one node update failure should not block updating other nodes.
Also the warning message easily flush the log file. This PR is just a quick
fix of this issue. More complete fix including make sure controller cache
up to date will be addressed in another PR.

Quobyte Volume plugin
@quofelix and myself developed a volume plugin for [Quobyte](http://www.quobyte.com) which is a software-defined storage solution. This PR allows Kubernetes users to mount a Quobyte Volume inside their containers over Kubernetes.
Here are some further informations about [Quobyte and Storage for containers](http://www.quobyte.com/containers)
Convert single GV and lists of GVs into an interface that can handle
more complex scenarios (everything internal, nothing supported). Pass
the interface down into conversion.

Implement dynamic provisioning (beta) of PersistentVolumes via StorageClass
Implemented according to PR #26908. There are several patches in this PR with one huge code regen inside.
* Please review the API changes (the first patch) carefully, sometimes I don't know what the code is doing...
* `PV.Spec.Class` and `PVC.Spec.Class` is not implemented, use annotation `volume.alpha.kubernetes.io/storage-class`
* See e2e test and integration test changes - Kubernetes won't provision a thing without explicit configuration of at least one `StorageClass` instance!
* Multiple provisioning volume plugins can coexist together, e.g. HostPath and AWS EBS. This is important for Gluster and RBD provisioners in #25026
* Contradicting the proposal, `claim.Selector` and `volume.alpha.kubernetes.io/storage-class` annotation are **not** mutually exclusive. They're both used for matching existing PVs. However, only `volume.alpha.kubernetes.io/storage-class` is used for provisioning, configuration of provisioning with `Selector` is left for (near) future.
* Documentation is missing. Can please someone write some while I am out?
For now, AWS volume plugin accepts classes with these parameters:
```
kind: StorageClass
metadata:
name: slow
provisionerType: kubernetes.io/aws-ebs
provisionerParameters:
type: io1
zone: us-east-1d
iopsPerGB: 10
```
* parameters are case-insensitive
* `type`: `io1`, `gp2`, `sc1`, `st1`. See AWS docs for details
* `iopsPerGB`: only for `io1` volumes. I/O operations per second per GiB. AWS volume plugin multiplies this with size of requested volume to compute IOPS of the volume and caps it at 20 000 IOPS (maximum supported by AWS, see AWS docs).
* of course, the plugin will use some defaults when a parameter is omitted in a `StorageClass` instance (`gp2` in the same zone as in 1.3).
GCE:
```
apiVersion: extensions/v1beta1
kind: StorageClass
metadata:
name: slow
provisionerType: kubernetes.io/gce-pd
provisionerParameters:
type: pd-standard
zone: us-central1-a
```
* `type`: `pd-standard` or `pd-ssd`
* `zone`: GCE zone
* of course, the plugin will use some defaults when a parameter is omitted in a `StorageClass` instance (SSD in the same zone as in 1.3 ?).

Fix deadlock possibility in federated informer
On cluster add subinformer locks and tries to add cluster to federated informer. When someone checks if everything is in sync federated informer is locked and then subinformer is inspected what apparently requires a lock. With really bad timing this can create a deadlock.
This PR ensures that there is always at most 1 lock taken in federated informer.

Add annotations to the PodSecurityPolicy Provider interface
@pweil- is this what you were thinking in terms of API changes? I really like to avoid functions with more than 2 return values, but couldn't think of a cleaner approach in this case.
